If you're looking for a stepless burr grinder with a small footprint and all metallic casing, Ascaso's I-Steel is a great option. It's simple, easy to use and allows you infinite adjustment to truly dial in your grind. Additionally, even its chute is metal -- unlike the plastics often found on other machines -- and some people really dig that. This comes with either flat burrs (i-Steel I-1) or conical burrs (i-Steel I-2).
